I usually specify both --target=mipsel-linux and --host=mipsel-linux,
because I find that some autoconf packages (NOT COMPILERS, yes, I
understand the difference) only cross-compile properly with --target,
while other packages only work with --host. In this case, I specified

I ran the ntpdc-layout program on my target, and it output the exact
same content as the layout.std file in the ntp-4.2.0 distribution. So
I know that I'm safe with the defaults, but the same can't necessarily
be said for other platforms.

Worked great, and was educational. Thank you for the patch!
